Alternative splicing of RNA transcripts allows a single gene to generate multiple products and is a key means of generating functionally diverse voltage-gated ion channels. Splicing can be regulated according to cell type, cell state, and stage of development to produce a bespoke complement of protein isoforms. Characterizing the identities of full-length transcript isoforms is essential in order to fully understand a gene's expression and function. However, the repertoire of transcript isoforms is not well characterized for most genes. Long read nanopore sequencing allows full-length isoforms to be sequenced, therefore identifying full-length transcripts. Using this approach, we recently discovered that the human CACNA1C gene gives rise to a far greater repertoire of splice isoforms than previously appreciated. Here we provide a detailed overview of the technical approach we used to achieve this. The method described in this chapter combines long read nanopore sequencing with PCR targeting to selectively sequence transcripts of a specific gene of interest.
